a few questions about SASS

I am interested in SASS. I plan on going to a event and observing, but I wanted a few questions answered.
First, do you have to dress up as a cowboy?
Are you required to have 2 revolvers, one lever action rifle and a shot gun to participate in anything in SASS? Is there special events that deal with just one of these fire arms? ie quick draw, shooting air born targets with a revolver ect ect
Is a .44 bp cap and ball revolver accepted, or does it have to be a cartridge?

I'm not a SASS member, so my knowledge is limited. I think you should be able to find individual firearms events and I see no reason why black powder wouldn't be acceptable. However, I'm just guessing because I've looked into it a bit.

Why not contact the local SASS chapter in your area and see what they have to say?

No quick draw and the only air born targets are shotgun poppers. Black powder revolvers are legal for most classes. Lever action rifle must be pistol caliber. Shotguns are SXS with no ejectors, safety may be disconnected. 97 Winchesters and 87 Winchesters and clones are legal but not the 93 or 93/97 hybrid. No other repeaters are legal and these may be loaded with two rounds only.
